闻亭公司培训DM642的内部资料一共有五天，里面包含讲解的ppt,文档，开发工具，课堂源码例子等。这是第三天内容.(Wintech DM642 training information, total of five parts, which contains explanations ppt, documentation, development tools, source code examples of class and so on.This is the 3rd part. )

Koch分形曲线计算地图边界，此程序能较好的计算任意凸图形边界长度。程序计算步骤为：提取图形边界，将边界点按与中心点所成角度排序，每隔一定角度取一边界点，对选取的边界点做3次迭代Koch分形(Koch fractal curve map boundary, this procedure can be better calculated arbitrary convex graphical boundary length. The program calculation steps: to extract graphical boundary, the boundary points and the center point of the angled Sort every angle to take a boundary point, done the 3 iterations Koch fractal selected border points)

pipelined ADC, 各种参数可调，最后包括fft分析和整个传输曲线(pipelined ADC, adjustable parameters, and finally including the entire transfer curve analysis and fft)

球面最小二乘拟合matlab程序。由离散的3D点拟合球面。(Least square fit of a sphere)

说明：  关于MATALAB的书籍文章很经典值得一看解压后必须使用超星浏览器观看(MATALAB article on classic books worth a visit after decompression must use a browser Chaoxing Views)

AR模型，用伯格法求谱估计曲线，算法简单实用(AR model method using Burg spectral estimation curve, the algorithm is simple and practical)

这是指图像拼接的一个MATLAB源码,不知道是否会对大伙有用.(This image is a mosaic of MATLAB source, do not know whether everyone would useful.)
